Product details
Overview
SMCJ60CHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of power rails and signal lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) under 10/1000 µs waveform - deployed in automotive power supply inputs and industrial motor drive control circuits.
For engineers reviewing the SMCJ60CHE3/57T datasheet, SMCJ60CHE3/57T pinout, SMCJ60CHE3/57T application, or SMCJ60CHE3/57T equivalent, key selection criteria include verified AEC-Q101 qualification, low incremental surge resistance, bi-directional-capable variant compatibility (e.g., SMCJ60CHE3/57T vs. SMCJ60CAHE3/57T), and thermal performance with RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ60CHE3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to transients. Its unidirectional polarity uses a cathode band marking, and it sustains 200 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave while maintaining clamping within 96.8 V at rated IPPM.
Thermally, it supports operation from –55 °C to +150 °C junction temperature, with RθJL = 15 °C/W enabling effective heat transfer to PCB leads. The device meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing due to its matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Power Input Protection | Industrial Motor Drive I/O Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and jump-start surges per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and GND to clamp transients before they reach LDOs or microcontrollers. Use Value: Limits peak voltage to ≤96.8 V during 15.5 A surge, preventing damage to downstream 3.3 V/5 V logic and analog sensors. |
Use Scenario: Safeguarding digital I/O lines of PLC output modules driving solenoids and relays. IC Role / Device Role / Timing Role: TVS mounted at connector interface to absorb inductive kickback from switched inductive loads. Use Value: Sub-ns response and 1500 W PPPM ensure reliable suppression of >100 V spikes without latch-up or failure. |
| Telecom DC Power Feeds | Consumer Power Adapter Outputs |
|
Use Scenario: Overvoltage protection on -48 V telecom rectifier outputs exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to system ground, absorbing common-mode transients on DC distribution bus. Use Value: 60 V VWM aligns with nominal -48 V systems; 96.8 V VC prevents overvoltage on downstream DC/DC converters. |
Use Scenario: Secondary-side surge protection in USB-C PD adapters and AC/DC wall adapters. IC Role / Device Role / Timing Role: TVS placed after secondary rectification to protect synchronous rectifiers and output capacitors. Use Value: Low RθJA and AEC-Q101 qualification support high-reliability consumer applications requiring >10-year field life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60AHE3/A | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (~150 °C/W) | Restricted to low-energy transients; unsuitable for ISO 7637-2 Pulse 5a or load dump. | Select when board space is constrained and surge energy is limited to <50 mJ. |
| SMCJ60CAHE3/57T | Bi-directional version; same VWM (60 V), identical PPPM (1500 W), but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where reverse polarity transients occur (e.g., RS-485, CAN FD). | Choose for bidirectional protection needs; not a drop-in replacement due to polarity and layout differences. |
Compared with SMAJ60AHE3/A and SMCJ60CAHE3/57T, the SMCJ60CHE3/57T delivers superior surge energy handling in a thermally optimized package while maintaining AEC-Q101 compliance - making it the preferred choice for high-reliability unidirectional DC rail protection where 1500 W clamping capability and low thermal resistance are mandatory.

FAQ
What is the clamping voltage of the SMCJ60CHE3/57T at its rated peak pulse current?
The SMCJ60CHE3/57T has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 15.5 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 96.8 V during a full-power transient event, provided the device is mounted on the recommended 8.0 mm × 8.0 mm copper pad layout. The SMCJ60CHE3/57T maintains this clamping performance across its qualified temperature range.
Is the SMCJ60CHE3/57T suitable for automotive applications?
Yes, the SMCJ60CHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body control modules, and ADAS power supplies. Its construction includes glass-passivated junction, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, and MSL Level 1 reflow compatibility - all validated per automotive reliability test standards. The SMCJ60CHE3/57T is listed in Vishay's AEC-Q101 qualified product portfolio for transient suppression.
How does the SMCJ60CHE3/57T differ from the bi-directional SMCJ60CAHE3/57T?
The SMCJ60CHE3/57T is unidirectional with cathode-band polarity marking and clamps only in reverse bias, whereas the SMCJ60CAHE3/57T is bi-directional with symmetrical clamping in both polarities and no polarity marking. Both share identical VWM (60 V), PPPM (1500 W), and DO-214AB packaging, but their PCB layouts differ due to polarity constraints. The SMCJ60CHE3/57T cannot replace SMCJ60CAHE3/57T in AC or floating-line applications without circuit redesign.
What is the thermal resistance of the SMCJ60CHE3/57T, and how does it affect PCB layout?
The SMCJ60CHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. This value assumes FR-4 board material and natural convection; reducing pad area increases RθJA and risks exceeding TJ max = +150 °C under repeated surges. For high-duty-cycle applications, the SMCJ60CHE3/57T benefits from additional thermal vias or internal ground planes to maintain safe junction temperatures.
Does the SMCJ60CHE3/57T meet RoHS and halogen-free requirements?
Yes, the SMCJ60CHE3/57T carries the HE3 suffix indicating RoHS-compliant construction per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. Vishay certifies that all HE3-suffix parts meet both environmental standards, with material declarations available via Vishay's official compliance portal. The SMCJ60CHE3/57T contains no brominated flame retardants, PVC, or antimony trioxide, and its molding compound achieves UL 94 V-0 flammability rating.
